Abstract: In this paper, by combing the variational methods and Trudinger-Moser inequality, we study the existence and multiplicity of the positive standing wave for the following Chern-Simons-Schrodinger equation $$-\Delta u+u +\lambda\left(\int_{0}^{\infty}\frac{h(s)}{s}u^{2}(s)ds+\frac{h^{2}(\vert x\vert)}{\vert x\vert^{2}}\right)u=f(x,u)+\epsilon k(x)\quad\quad \text{in}\,\,\mathbb{R}^2, \\$$ where $h(s)=\int_{0}^{s}\frac{l}{2}u^{2}(l)dl$, $\lambda>0$ and the nonlinearity $f:\mathbb{R}^2\times \mathbb{R}\rightarrow \mathbb{R}$ behaves like $\text{exp}(\alpha\vert u\vert^{2})$ as $\vert u\vert\rightarrow \infty$. For the case $\epsilon=0$, we can get a mountain-pass type solution.

Abstract: In this paper, we study the following Chern-Simons-Schrodinger system − Δ u + u + ( h 2 ( | x | ) | x | 2 + ∫ | x | ∞ h ( s ) s u 2 ( s ) d s ) u = f ( u ) in R 2 , where h ( s ) = 1 2 ∫ 0 s r u 2 ( r ) d r and the nonlinearity f ∈ C ( R , R ) . If f satisfies asymptotically 3-linear at infinity, we establish the existence of ground state solutions by using general minimax principle. Moreover, we obtain the multiplicity of solutions by a mountain pass approach introduced by Hirata, Ikoma and Tanaka (2010) [7] .

Abstract: In this paper, we consider the equation \begin{aligned} -\varepsilon ^{2}\Delta u+ V(x)u+\left( A_{0}(u)+A_{1}^{2}(u)+A_{2}^{2}(u)\right) u=f(u) \ \ \ \ \mathrm {in} ~ H^{1}({\mathbb {R}}^{2}), \end{aligned} where $$\varepsilon$$ is a small parameter, V is the external potential, $$A_i(i=0,1,2)$$ is the gauge field and $$f\in C({\mathbb {R}}, {\mathbb {R}})$$ is 5-superlinear growth. By using variational methods and analytic technique, we prove that this system possesses a ground state solution $$u_\varepsilon$$ . Moreover, our results show that, as $$\varepsilon \rightarrow 0$$ , the global maximum point $$x_\varepsilon$$ of $$u_\varepsilon$$ must concentrate at the global minimum point $$x_0$$ of V.

Abstract: In this paper, we investigate the following Chern-Simons-Schrodinger system { − Δ u + V ( x ) u + A 0 u + A 1 2 u + A 2 2 u = f ( x , u ) , x ∈ R 2 , ∂ 1 A 2 − ∂ 2 A 1 = − 1 2 u 2 , ∂ 1 A 1 + ∂ 2 A 2 = 0 , ∂ 1 A 0 = A 2 u 2 , ∂ 2 A 0 = − A 1 u 2 , where V is the potential, ∂ 1 = ∂ ∂ x 1 , ∂ 2 = ∂ ∂ x 2 for x = ( x 1 , x 2 ) ∈ R 2 , A j : R 2 → R is the gauge field ( j = 0 , 1 , 2 ) and the nonlinearity f ( x , s ) ∈ C ( R 2 × R , R ) behaves like e 4 π s 2 as | s | → + ∞ . If V and f are both asymptotically periodic at infinity, we prove the existence of positive ground state solutions by combining the Nehari manifold methods with the Trudinger-Moser inequality.

Abstract: In this paper, we study the following Chern–Simons–Schrodinger equation \begin{aligned} {\left\{ \begin{array}{ll} \displaystyle -\Delta u+\omega u+\lambda \Big (\frac{h^{2}(|x|)}{|x|^{2}}+ \int _{|x|}^{+\infty }\frac{h(s)}{s}u^{2}(s)\hbox {d}s\Big )u=g(u) \quad \text{ in }\ {\mathbb {R}}^{2},\\ \displaystyle u\in H_r^1({\mathbb {R}}^{2}), \end{array}\right. } \end{aligned} where $$\omega ,\lambda >0$$ and $$h(s)=\frac{1}{2}\int _{0}^{s}ru^{2}(r)\hbox {d}r$$ . Since the nonlinearity g is asymptotically 5-linear at infinity, there would be a competition between g and the nonlocal term. By constrained minimization arguments and the quantitative deformation lemma, we prove the existence of least energy sign-changing radial solution, which changes sign exactly once. Further, we study the concentration of the least energy sign-changing radial solutions as $$\lambda \rightarrow 0$$ .

Abstract: We construct a nonrelativistic field theory for the second-quantized N-body system of point particles with Chern-Simons interactions. Various properties of this model are discussed: its obvious and hidden symmetries, its relation to a relativistic field theory, and its supersymmetric formulation. We present classical, static solutions--solitons--that satisfy a self-dual equation, which is equivalent to the Liouville equation; hence, it is completely solvable. The dynamical role of the Chern-Simons interaction is demonstrated: the interaction does not merely change statistics but also provides the forces that bind the classical solitons.
